Do you still have the pro upgrade? If you scroll the effects list all the way to the right, does it ask you if you want to upgrade or does it show all the effects? If you lost your upgrade somehow, try tapping the gear, then scroll down and select "Restore Pro Upgrade" on the settings.

You should have a bunch of buttons at the bottom of the screen when looking at Mount Rushmore, letting you select different faces and mouths. I'm not sure why they would be missing; it works for me. But other people have complained about the same thing.
